We have identified three steps in mean global temperatures since 1970: one in 1979, one in 1988 and one in 1998. These three steps alone conspicuously and remarkably contain the entire modern era ‘global warming’ observed to occur between the late 70s and the early 00s, a period of about 20-25 years, depending on how you look at it. This means that outside these three distinct and sudden upward jolts, there has been no discernable ‘global warming’ going on at all for the duration of at least the last 50 years.
So how, then, did these three prominent steps in global temperatures come about?
It has long been known that the climate regime (the general state, arrangement and operative processes of the coupled ocean/atmosphere condition) of the Pan-Pacific basin changed fundamentally and abruptly in 1976/77. Many studies have documented this. Something big happened in the Pacific Ocean that year. This ‘thing’ has been dubbed ‘The Great Pacific Climate Shift’ (GPCS). Continue reading
